I Have a 2000 silverado with a 5.3l. I have everything installed. The indicator light flashes code 18.Does anybody have a wiring diag for it. I think everything is where its supposed.Theres this little box that connects to the Whipple computer that has a ground three wires that come from the whipple computer and these two little connectors Red and gray. No idea where they go.There was also 4 to 5 wires that were suppose to be tied into the vcm and i did that.Not sure on any of this so if someone could help me hook this up correctly i would greatly appreciate it. I dont want to ruin my motor. Thanks a look forward to reply in how to properly hook this thing up..

i would contact whipple directly, i don`t have any diagrams for that setup, have you considered a custom ECM tune? thats the route i went with, not having to rely on and accessory electrical.

Anyone know how this wiring hooks up for this charger?I have all the wires hooked up for the main auxiliary fuel injectors but there is this other little computer thing that runs to the passenger side that connects the the whipple harness and has a ground, a little red wire with a male to female connector and a gray wire with a male to female connector. No clue where these go.The indicator light flashes code 18.Says not connected to the MAS sensor.In the manual it does not show this little box, or in the wiring diagram. I'm not sure if the were suppose to hook up to the blow of valve.I didnot see any wiring on it. Any info would greatly help

anyone please help
